TECHNICAL FIELD

The present disclosure relates to an optical lens assembly, a device,and an image forming method, for example, an optical lens assembly, adevice, and an image forming method provided in an electronic device.

BACKGROUND ART

Various services and additional functions provided by electronic devicesare gradually expanding. An electronic device, e.g., a mobile device ora user device, may provide various services via various sensor modules.An electronic device may provide a multimedia service, for example, apicture service or video service. As electronic devices have become morewidely used, utilization of a camera functionally connected to anelectronic device has gradually increased. According to user demand,camera performance and/or resolution in an electronic device isgradually improving. Various kinds of scenes, people, or selfies may becaptured by a camera of an electronic device. In addition, suchmultimedia, for example, pictures or videos, may be shared on a socialnetwork site or other media.

As semiconductor and display techniques have developed, optical lensassemblies for a camera in a mobile device, e.g., from a low resolutionto a high resolution, from a small-sized sensor format to a large-sizedsensor format, for example, from a ⅛″ sensor to a ½″ sensor, and from alens assembly with a smaller number of lenses to a lens assembly with agreater number of lenses, are being developed.

DESCRIPTION OF EMBODIMENTS Technical Problem

When an optical lens assembly for a camera is mounted in an electronicdevice, multimedia, e.g., photos or videos may be generated, and themultimedia may be provided to a user. In the market of mobile devices,there have been trends to reduce a thickness of an electronic device bymounting an optical lens assembly in the electronic device. For example,a thickness of an electronic device may be reduced to about 10 mm to 6mm. Such trends may be incompatible with the increase in the number oflenses and the increase in sensor size. For example, it may be difficultto implement high-specification performance required by a user by usinga smaller number of lenses. Also, it may be difficult to mount anoptical lens assembly that satisfies optical characteristics and/oraberration characteristics while trying to make an electronic devicethinner.

One or more embodiments of the present disclosure provide a small-sizedtelephoto optical lens assembly in, for example, an electronic device(e.g., a portable terminal).
